Hi..
i dont know my theorems...tinkin bout pickin 5 theorems and just learnin them!! Whats d stori wit evry1 else? and what one's do ya's think will cum up?

The second last one (if triangles are equilangular). Also perhaps the one about the circle bisecting the chord....(cant think of its proper name)

Look at the papers- dont learn the ones that came up last year

Timans

Doubt Pythagorus will come up as that came up last year.

i got told by two different maths teachers i know that there is a good chance of the last 3 coming up, personally, id say the ninth one defo(wierd triangle one) and poss the 8th(bisectin one) but pythargoras came up last year, maybe it wasnt well answered, i cant personaly see pythargoras coming up again tbh


was just reading the chief examiners report on maths for last year, pythargoras wsa asked in question 4, part B,this question had an average mark of 30.5, one of the lower average marks,

what it says about the answers, you can judge yourself;

chief examiners report wrote:

In the proof of Pythagoras theorem, both methods on the marking scheme were equally popular, but usually there were more errors with the square method. Common errors in the similar triangles method were: step 3 of the marking scheme – not giving reasons; step 2 of the marking scheme – construction incomplete; step 5 of the marking scheme – sign errors. Common errors in the alternative method were: not proving ⎥∠4⎥ = 90; not indicating each side of quadrilateral equal in length; not mentioning congruence of triangles; construction was very inaccurate. Candidates frequently lost 6 or 9 marks for this method as many attempted to present briefer versions with elements either missing altogether or incomplete.

Yea might just learn those ones haha...my teacher told us to make sure me know theorem 1...even tho its easy make sure we know it..cause sumtimes ppl just dont bother learnin it cause its easy den its asked and they dont kno it...I need to learn the constructions aswell!! that incircle stuff!:eek:

Joseph

Similar Triangles will come up, and maybe a parallelogram.

I am not worried at all what comes up. I know all off now and test myself regularly in all of them.

Honestly though you need to grasp the idea behind all because any can be needed for question and not proofs.

Exactly.

Does anybody have the heading/title for Theorem 15? I don't need the proof just the heading - thanks

Joseph

Theorem 15? What are you on about lol

diamonds&cream

Its the one after 'A Diagonal bisects the area of a parralelogram' (#14) and before 'Similar Triangles' (#16).

All my Theorems are numbered 1 to 17, I am just missing 15 - Are yours not?

diamonds&cream

have it now, deductions & constructions (circumcircle & incircle) were numbered in my list, which is why it seems I have so many

Joseph

ah cause there is only 10, (11 maybe 12 you have to know)

qwertplaywert

10 you have to know i believe
i learned the first 2[ the 3rd came up last year , so wont be up this year] and 9 and 10[praanglues].....the circle ones i couldnt understand, hope they dont come up!

highlydebased

Apparently their not supposed to ask the deductions any more

Joseph

Really?? That would be nice! But they'll still come in the cuts I reckon

timmywex

well....everyone was wrong!!

matdabomb

Dam did not see the thread before it was running. But I quote myself from the Maths paper 1 thread. I said that Theorem 9 WONT come up, Was so sure and because alot of kids in the class were also sure it would come up made a nice little profit
